As of JDK 27, Oracle engineers will thus stop maintaining the macOS/x64 port
Deprecate the macOS/x64 port, with the intent to remove it in a future release, in order to reduce maintenance costs.
Apple has transitioned its hardware products to the AArch64 processor architecture and is phasing out support for x64. Oracle engineers will thus stop maintaining the macOS/x64 port as of JDK 27. Maintaining the port is a significant burden.
An attempt to configure a macOS/x64 build will produce:
The new build-configuration option --enable-deprecated-ports will suppress the error and continue:
There will be no guarantee that the port will build, much less function.
In order not to block mainline development, macOS/x64 will be disabled by default in the JDK repository’s GitHub actions.
